China´s surging economy runs mostly on coal, which slakes four-fifths of the country´s thirst for electricity. And all over China, the consequences of that dependence are apparent: Its major cities are swathed in deadly smog, regional blackouts ensue when coal trains bog down on clogged rail networks, and coal mining routinely kills more than 2000 people a year. China desperately needs alternatives to coal-fired power.
